Benefits of TESA UPD

Permits over 90% of a 122-piece set to be checked using the same reference gauge block.

Allows the reference gauge set to be reduced by nearly 80% against the ones needed until now.

Provides substantial savings in the gauge block supply and recalibration through reduced set compositions.

Enables direct measurement of gauge blocks that cannot be compared with other existing gauge blocks due to their unusual nominal lengths.

Allows the gauge blocks of same nominal lengths to be measured by comparison as usual.

Enhances the measuring conditions, thus permitting all measurements to be taken with a lower uncertainty.

Reduce the number of systematic errors through limited length related influences of both the upper probe A and the gauge block to be compared.

Standard	EN ISO 3650
Maximum permissible errors	Provided all metrological conditions are met, the reliability of the comparator used for direct measurement of steel gauge blocks is expressed as follows: – Repeatability limit (with no influence of external temperature): 0,015 μm – Uncertainty of measurement: U = ± (0,05 + 0,5 · L) μm (L in m) Condition requires the use of reference standards whose measurement uncertainty is equal to: – U ≤ ± 0,015 μm for the comparator – U ≤ ± (0,02 + 0,2·L) μm (L in m) for the gauge blocks
Function(s)	Measuring configuration: 2 probes connected in sum measurement (function +A+B) with mechanical contact with the measuring face. Measuring points: On the reference gauge block: at the centre of the measuring face (point R). On the gauge block to be measured: at the centre (point 1) as well as the 4 corners of the measuring face, each lying 2 mm away from the adjacent faces (points 2 to 5). Central length lc is defined by probing both points R and 1. Establishing lengths “at any point” requires measurements to be taken at points R plus 1 to 5. Variation in length v is the result of measurements taken at points 1 to 5.
